In an extremely limited number of cases, the published article may need to be removed from our online platform. It will only happen that if an article is clearly defamatory, or violate another person’s legal rights, or where the article is located, or we have the strong reason to expect, being the subject of a court order, or where the article, if acted upon, may pose a serious health risk. In such circumstances, while the metadata (i.e. title and author information)of the article will be retained, the text will be replaced with a screen indicating that the article has been removed for legal reasons.
